SAP-C02 Design for New Solutions Practice Question
A company is designing a multi-tier web application on AWS. They want to ensure that the web tier can scale automatically based on CPU utilization. Which AWS service should they use?
⚠ Common exam trap
Watch out — candidates often confuse Elastic Load Balancing with automatic scaling, but ELB only distributes traffic and does not add or remove instances; the Auto Scaling group is the service that actually scales the compute capacity.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Auto Scaling groups
Auto Scaling groups (Option C) are the correct service because they directly manage the automatic scaling of EC2 instances based on defined policies, such as a target CPU utilization threshold. When CPU utilization exceeds the threshold, the Auto Scaling group launches new instances to handle the load, and it terminates instances when utilization drops, ensuring the web tier scales automatically.
